What would cause a 300 Savage casing to show a deformation on the bottom 3/8" on the fired casing??
1st- Hornady 150 gr SST
2nd- Federal 150 gr SP
3rd- Vintage Peters 180 gr SP Both the Hornaday and Federal casings show a deformation on the bottom 3/8" of the casing
3rd. Vintage Peters showed not deformation after firing The ammo is to pricey to keep buying different brands and grain. The Peters 180 gr showed no deformation like the other 2.
Im curious if the composition of the brass?
